Welcome to EBN! This little gal is still a pup-and surely has not been given any lessons. To teach her it is best to have her in the kitchen by herself to eat=don't know if you feed them both together-but we don't want pup worrying about someone getting her food. You can get a special dish that looks like a maze such as the one pictured-or there are many other kinds. You must teach her to sit, before giving her the food. Do not give her food or treat until she does sit. If would be easier to teach with a treat first, rather than her food-she won't be quite as excited. It is just a matter of not giving in until she does sit-even if it is for one second. When she does praise her to high heaven and give the treat. Eventually she will get it! Persistence on your part. Mine all sit when they see the food bowlcoming. At least they learned that!>>>>>>agression is alot different than excitement! Whole different ball game....I would also recommend that you put your hand in her dish, pet her take the dish away for a second, so she does not get food agressive.
